SKATE-ROLLER.

SPECIFICATION forming part of Letters Patent No. 404,547, dated June 4,1889.

Application filed April 11, 1887.

To all whom it Hwy concern:

Be it known that 1, CHARLES J. KINTNER, formerly of lVashington,District of Columbia, now residing in Philadelphia, Pennsylvania, havemade certain new Improvements in Roller-Skates, of which the followingspecification, taken in connection with the accompanying drawings, is afull, clear, and exact description.

My invention relates particularly to improvements in the rollers ofroller-skates and analogous devices, and has for its object theprevention of oil used in oiling said parts fr'om running or dripping onthe floor; and to this end it consists, first, in providing said rollerswith retaining-grooves on their lateral faces filled with absorbentmaterial to catch the oil as it runs from the axles of the skates downor over said lateral faces; second, in providing an absorbent packing tohold against the faces of the rollers either by devices to behereinafter described or by its own inherent properties.

Prior to my invention, so far as I am aware, no provision was ever madefor common and well-known forms of skating-rollers whereby oil could bekept from trickling down onto the face of the roller and ultimately tothe floor of the rink, thereby soiling the floor and also endangeringthe skater.

I am aware that self-oiling rollers have been provided withretaining-cups and packing for the purpose of retaining the oil; but myinvention has especial reference to well-known forms of rollers whichmay be oiled while being used by simply dripping the oil on the end ofthe roller-axles in a manner well understood.

In the drawings, Figure 1 is a side elevation of a skating-roller, partbroken away to show my improvement. Fig. 2 is a cross-section of Fig. 1.Fig. 3 is across-section, and Fig. 4 a side elevation, showing amodified form with packing and retaining-ring. Fig.5 is an elevationshowing the packing wound about a retaining-ring.

roller, showing an additional modification with two grooves on each faceand felt or other rigid absorbent material in place, no retaining-ringbeing required. I

Referring now to the drawings by detail, A

represents a skate-roller, and B the body thereof. In its lateral facesare out two grooves O, of sufficient depth to hold such oil as maytrickle down from axle G.

R is a spring-ring of such size that it will retain the absorbentpacking P, Figs. 1, 2, 3, and 4, in place. This packing may be of anyabsorbent material, and may be either wrapped around the ring, as shownin Figs. 1, 2, and 5, or may-lie in the grooves and be held in place bythe ring resting directly upon it, as shown in Figs. 3 and 47. In Fig. 6is shown a modified form of packing, consisting of thick felt or otherequivalent absorbent material-as sponge, cork, porous rubber, &c.-whichis of sufficient body to sustain itself in place when forced into thegrooves C O, and may, if desired, have a slit S to allow it to be easilyforced into grooves O.

O O are oil-holes to afford free access for the oil to the axle G.

E is the linchpin, and F the washer, of wellknown forms.

9 is an additional groove for oiling purposes, as will be explained.

The operation is as follows: 011 oiling the I skate, in the usualmanner, by pouring oil upon the end of axle G and about washer F, itruns in between the roller and axle, but more or less waste occurs, andafter the skater has been skating a brief time the oil is forced bycentrifugal force along the lateral faces of the roller in radial lines.By my improvement the absorbent takes it up and holds it, so that itcannot pass to the floor. When the absorbent material has becomethoroughly saturated with oil, it may be removed, and when sufficientquantity of such material has collected it may be put in an oil-pressand the oil removed, thus saving oil which was before wasted.

It will be observed that the outer ends of oil-holes O 0, Fig. 6, entera groove g, which runs entirely around washer F. This groove is to catchthe oil from the can and direct it toward the oil-holes, and may have anogee shape similar to groove 0, if desired, so as to keep as much oil aspossible away from the absorbent P or second groove 0. It will beobserved that this groove lies entirely without washer F, so that allthe oil poured upon the end of axle G and washer F will either godirectly inside or find its way to said groove and ultimately inside,leaving small opportunity for any oil to drip onto the absorbingmaterial or run into the second groove 0.

In place of the grooves, I may simply cut a later. 1 ring-groove on eachface of the roller of sufficient depth to hold the absorbent materialand then glue said absorbent material directly in such groove when theroller is made. Each roller so made would be complete and the felt wouldnot be changed. Such form, however, I do not prefer, but merely describeit as an equivalent which may be used, my most desirable form being thatwhich utilizes the felt self-retaining packing and the oil-holes andgroove.

I do not limit myself to the use of this improved oil-retainin g devicewith skate-rollers, as it obviously has many other analogous uses, as inband or belt pulleys, truck-wheels, and kindred devices.

Having thus fully described my invention, what I desire to secure byLetters Patent of the United States is- 1. In a rollcr-skate,a rollerhaving grooves in its lateral faces and absorbent material located insaid grooves for retaining the waste oil, substantially as described.

2. In a roller-skate,a roller having grooves in its lateral faces,absorbent material in said grooves, and means for retaining saidabsorbent material in place, substantially as described.

33. In a roller-skate,a roller having grooves in its lateral faces forcatching the drip from the axle, in combination with oil-ducts runningtoward the center of the wheel, substantially as described.

4:. In a roller-skate, a roller having grooves in its lateral faces,with absorbent material located therein, in combination with oil-ductsfor conducting the oil to the axle of the skate.

5. In a roller-skate, a roller having grooves in its lateral faces forretaining the oil-drip, in combination with an oiling-groove andoilducts, substantially as described.

In testimony whereof I set my hand this 11th day of April, 1885.

CHARLES J. KININER.
